Hi Folks!

I have an editbox which I want to use as password box.

1. when the text = 'Geef wachtwoord in'  It should be cleared when the user clicks in it
2. It should show * instead of the password characters
3. When the user clicks somewhere else ie changed his mind and does soemthing else, it should show 'Geef wachtwoord in'
4. It should validate the input, password will be 1234 thus 4 numbers

If you need more info (or more points :)) please ask,

Regards,

Peter

you said the password is all numbers. "4. It should validate the input, password will be 1234 thus 4 numbers"

Hi ciuly,

I apologize, I was wrong it does work thanks! Validating the input by means of the button click, involves no rocket science right?

Regards,

Peter
